摘要： Access terminals are adapted to facilitate estimation of signal-to-noise ratios for received wireless transmissions. According to at least one example, a wireless communication device can receive a plurality of data symbols. The wireless communication device can determine a first estimate of a signal-to-noise ratio based on first estimates of a signal power and a noise power associated with the plurality of received data symbols. When the first estimate of the signal-to-noise ratio is below a predetermined threshold, a second estimate of the signal-to-noise ratio can be determined based on second estimates of the signal power and the noise power for the received data symbols. Other aspects, embodiments, and features are also included.

摘要： A receiver (FIG. 3) receives FSK and coherent 8PSK protocols. A selectively configurable processor (20) demodulates the message signals, and includes a demodulator (50-58) that derives in-phase and quadrature signals based on the message signals. A phase detector (60-64) is responsive to the in-phase and quadrature signals and delayed in-phase and quadrature signals to derive a phase signal. A selector (26) is responsive to the in-phase and quadrature signals to selectively connect a loop filter (66) between the phase detector and the demodulator. When the selector (26) connects the filter (66) between the phase detector (60-64) and demodulator (50-58), the demodulator is responsive to filtered phase signals to lock onto a frequency of the message signals so that the processor (20) operates as a phase locked loop to demodulate coherent modulated signals. When the selector (26) disconnects the filter (66) from between the phase detector (60-64) and the demodulator (50-58), the demodulator demodulates non-coherent modulated signals and the phase detector supplies a phase signal representing the slope of the phase of the demodulated signal.

摘要： On the transmitter side, a known signal of continuous Np symbols is periodically inserted into an information signal of (NF-Np) symbols, and a signal of NF symbols is transmitted. On the receiver side, the transmitted signal of NF symbols is received, the frequency difference is estimated from the transmitted signal, and frequency control is automatically made. Specifically, on the receiver side, from the received transmitted signal and a sinusoidal signal outputted from an oscillator, analog baseband signals of the I and Q channels are outputted, the analog baseband signals are converted to digital baseband signals, the phase difference of one symbol period is estimated from the digital baseband signals, integration by cyclic addition of the estimated value of the phase difference, and the frequency difference is eliminated from the digital baseband signals by using the results of the integration.

摘要： A television receiver system capable of receiving and demodulating television signal information content that has been modulated and transmitted in accordance with a variety of modulation formats is disclosed. In particular, the system is able to accommodate receipt and demodulation of at least 8 and 16-VSB modulated signals in order to support US HDTV applications, as well as 64 and 256-QAM modulated signals, for European and potential US CATV implementations. The system includes carrier and timing recovery loops adapted to operate on an enhanced pilot signal as well as decision directed carrier phase recovery loops. Phase detectors operate on I and Q rail signals, or generate a Q rail from a Hilbert transform of the I rail. Decision directed loops incorporate a trellis decoder in order to operate on sequence estimated decisions for improved reliability in poor SNR environments.

摘要： The invention relates to a method enabling simple synchronization of a receiver system with a transmitter system during transmission of an energy dispersed QPSK signal which is composed of two mixed products on the transmitter end; the mixed product from the I-signal and the transmission carrier, and the mixed product from the Q-signal and the send carrier displaced by 90 DEG . In order to allow for problem-free synchronisation of the receiver system with the transmitter system, the invention provides that the amplitude of the SQ signal is measured at the moment the rising edge of the SI signal passes through zero or the amplitude of the SI signal is measured when the falling edge of the SI signal passes through zero to determine the deviation in synchronism between the receiver carrier and the transmission carrier, and that the frequency of the receiver carrier varies in such a way that the amplitude of an error signal obtained using said measurement is zero. Measurement is carried out using the smallest possible number of measured values.

摘要： A digital loop filter in the carrier-recovery loop of a digital communications receiver. The recovery loop is a PLL that keeps the receiver oscillator locked to the carrier wave, and the loop filter provides control over the PLL's frequency response by conditioning an error signal that is fed back to the receiver oscillator. In the present invention, the error signal is a digital signal, and the loop filter is implemented in digital hardward. With this implementation the characteristics of the loop filter are determined by logic design rather than by physical features of analog components, thereby giving this filter a more precise function than one with analog integrators. This implementation is also immune to the low tolerances typical of the manufacturing process for analog devices (especially on monolithic circuits), and is more easily adjusted than its analog counterparts. Two gain coefficients characterize the loop filter in the present invention. These gain coefficients are chosen to be powers of two, simplifying the process of multiplying them with the digital error signal. The gain coefficients are read from a memory, making the loop filter easily programmable. By changing the gain coefficients during operation of the receiver, the carrier-recovery loop can be placed in one of the several operating modes, including acquisition, tracking, and hold. The receiver can be configured with the appropriate values of the gain coefficients for each operating mode during the initial assembly and during subsequent reconfigurations.

摘要： A carrier wave phase-modulated signal having 2M states, M being an integer, is demodulated by converting it into a quadrature two-way baseband signal by multiplying it by a local osciallator signal (20) at the translated carrier frequency, and digitising the baseband signal by sampling it at the modulating signal clock frequency. The signal clock is recovered by setting the phase of a bit frequency stabilised local clock (32) and seeking the minimum inter-symbol interference before recovering the carrier.
